I'm (kinda) new to electronics and I have a simple question... So, I have a phone charger and I cut the wire because I wanted to connect the PWR and the GRD to another circuit. But when I connected the multimeter to the wires I get no readings. I believe this has to do with the wire (it has multiple copper wires...)
I'm used to work with simple wires on arduino (not the copper ones) and this may be a dumb question but i'm really lost here :(
